An ion guide or ion trap that comprises a plurality of electrodes () is disclosed. The ion guide or ion trap includes a detector () that can detect light or particles () emitted from the ion guide or ion trap due to electrical breakdown, and a control circuit () that can control the ion guide or ion trap in response to the detector () detecting light or particles () emitted from the ion guide or ion trap.

Ion guide

A mass spectrometer is disclosed comprising an ion optics device housing having one or more external electrical connectors () provided thereon. An ion optics device () is arranged inside the ion optics device housing, the ion optics device () comprising one or more electrodes for manipulating ions, the one or more electrodes being electrically connected to the one or more external electrical connectors () provided on the ion optics device housing. A voltage supply housing () is provided having one or more external electrical connectors provided thereon. One or more voltage supplies are arranged inside the voltage supply housing (), the one or more voltage supplies being in electrical communication with the one or more external electrical connectors provided on the voltage supply housing. The one or more external electrical connectors provided on the voltage supply housing are directly physically and electrically connected to the one or more external electrical connectors () provided on the ion optics device housing.

Mass spectrometer

An ion guide is disclosed that comprises a plurality of electrodes arranged to form a multipole ion guide and one or more rigid support members. The plurality of electrodes comprises one or more groups of electrodes, and each group of electrodes comprises plural electrodes that are axially spaced apart from one another. The electrodes of one or more groups of electrodes are attached to one of the one or more rigid support members. One or more of the electrodes comprises a curved metal sheet, plate or strip.
